Today, Thurber studies math for 15 minutes and he studies science for 75 minutes. From now on, Thurber plans to study math for 50 minutes per day and to study science for 30 minutes per day. Will Thurber ever have studied the same total amount of time for both math and science? Explain. Use the drop-down menus to complete the sentence. days from today, Thurber will have studied of math and minutes of science.
Answer:
3 days
Step-by-step explanation:
Given that :
Today :
Study time for math = 15 minutes
Study time for science = 75 minutes
Subsequent days :
Study time for math = 50 minutes
Study time for science = 30 minutes
Let the number of days when study time for math and science will be the same = x
15 + 50x = 75 + 30x
50x - 30x = 75 - 15
20x = 60
x = 60 / 20
x = 3

|-3/4+1/8|- (2/3+1/6)
Answer:
-5/24
Step-by-step explanation:
-3/4 = -6/8
-6/8 + 1/8 = -5/8
|-5/8| = 5/8
2/3 = 4/6
4/6 + 1/6 = 5/6
5/8 - 5/6 = 15/24 - 20/24
15/24 + (-20/24) = -5/24

Jason used 0.5 cups or kernels to make 16 cups of popcorn. How many cups of popcorn would he make if he used 0.75 cups of kernels?
Please explain answer
Answer:
24 cups of popcorn
Step-by-step explanation:
Let x represent the number of cups of popcorn that can be made from 0.75 cups of kernels. We know that 0.5 cups of kernels is used to make 16 cups of popcorn. Therefore, to calculate the number of cups of popcorn that can be made from 0.75 cups of kernels we use the equation:
x / 0.75 cups of kernels = 16 cups of popcorn / 0.5 cups of kernels
multiplying through by 0.75 cups of kernels gives:
(x / 0.75 cups of kernels) * 0.75 cups of kernels = (16 cups of popcorn / 0.5 cups of popcorn) * 0.75 cups of kernels
x = 24 cups of popcorn

Choose 6 of them. Repetition is allowed, and order matters.
There are 10⁶ possible choices.
There are 8×10⁶ possible phone numbers.
Find the equation of the linear function represented by the table below in slope-
intercept form.
Answer:
[tex]y = x +2[/tex]
Step-by-step explanation:
Given
The attached table
Required
Determine the equation
First, calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Where
[tex](x_1,y_1) = (-3,-1)[/tex]
[tex](x_2,y_2) = (1,3)[/tex]
So, we have:
[tex]m = \frac{3 - (-1)}{1 - (-3)}[/tex]
[tex]m = \frac{3 +1}{1 +3}[/tex]
[tex]m = \frac{4}{4}[/tex]
[tex]m =1[/tex]
The equation in slope intercept form is calculated using
[tex]y = m(x - x_1) + y_1[/tex]
This gives:
[tex]y = 1(x - (-3)) -1[/tex]
[tex]y = 1(x +3) -1[/tex]
[tex]y = x +3 -1[/tex]
[tex]y = x +2[/tex]
Solve the system of equations, y = x – 3 and y = –2x + 6, using the substitution method.

Science
Which weather data would best indicate that monsoon rains are coming to Arizona on a hot day in August? Choose the three correct answers.
A
wind blowing from the south
B
high air pressure
C
high humidity
D
low air pressure
E
wind blowing from the north
F
low humidity
Answer:
A. wind blowing from the south
D. Low air pressure
C. High humidity
Step-by-step explanation:
High humidity can cause the clouds to shower. When the humidity is reached to 100 percent the rain starts. For the raining system the air pressure should be low. The low air pressure often indicates the thunderstorm. Cloud are ready filled with water and when the air pressure is lowered the rain starts.

Please help!!! 10 points for it!!
Answer:
Step-by-step explanation:
x = 180 - ((180-96)+(180-130))
x = 180 - (84+50)
x = 46°
Answer:
x = 46 degrees
Step-by-step explanation:
180 - 130 = 50
180 - 96 = 84
50 + 84 = 134
180 - 134 = 46
On the package for a certain brand of spinach seeds there is a guarantee that, if the printed instructions are followed, of planted seeds will germinate. A random sample of seeds is chosen. If these seeds are planted according to the instructions, find the probability that of them germinate.
The question is incomplete. Here is the complete question.
On the package for a certain brand of spinach seeds there is a guarantee that, if the printed instructions are followed, 63% of planted seeds will germinate. A random sample of 9 seeds is chosen. If these seeds are planted according to the instructions, find the probability that 4 or 5 of them germinate. Do not round your intermiediate computations, and round your answer to three decimal places.
Answer: P(4<X<5) = 0.624
Step-by-step explanation: The probability of a seed germinate is a Binomial Distribution, i.e., a discrete probability distribution of the number of successes in a sequence of n independents experiments.
This distribution can be approximated to normal distribution by determining the values of mean and standard deviation population:
[tex]\mu=np[/tex]
[tex]\sigma=\sqrt{np(1-p)}[/tex]
where
n is the sample quantity
p is proportion of successes
For the spinach seeds:
Mean is
[tex]\mu=9(0.65)[/tex]
[tex]\mu=[/tex] 5.85
Standard deviation is
[tex]\sigma=\sqrt{9.0.65(1-0.65)}[/tex]
[tex]\sigma=[/tex] 1.431
Now, use
[tex]z=\frac{x-\mu}{\sigma}[/tex]
to convert into a standard normal distribution.
The probability we want is between 2 values: P(4<X<5).
Therefore, we have to convert those two values:
For X = 4:
[tex]z=\frac{4-5.85}{1.431}[/tex]
z = -1.29
For X = 5:
[tex]z=\frac{5-5.85}{1.431}[/tex]
z = -0.59
Using z-table:
P(X>4) = 1 - P(z< -1.29) = 0.9015
P(X<5) = P(z< -0.59) = 0.2776
The probability will be
P(4<X<5) = P(X>4) - P(X<5)
P(4<X<5) = 0.9015 - 0.2776
P(4<X<5) = 0.624
The probability of 4 or 5 seeds germinate is 0.624.

The graph of the reciprocal parent function, f(x) = 1, is shifted 5 units up
and 8 units to the left to create the graph of g(x). What function is g(x)?
Answer:
A. 1/(x + 8) + 5.
Step-by-step explanation:
Staring with 1/x a shift up of 5 units makes it 1/x + 5.
A shift of 8 to the left makes it 1/(x + 8) + 5
